DOOR-HAN GER.

To all whom it may concern:

Be it known that I, Gnonon LEoxi-mnn Scnxnrr, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Door-Hanger, of which the following is a full, clear, and exact description.

The invention is an iinpiovement in door hangers and tracks for sliding doors, primarily such as include free and lineally movable roller bearings between the track and hanger, and has in view a hanger and track by which the door may have an increased travel over doors supported on tracks and hangers of the same working length as hitherto constructed.

To this end the invention in general consists of a fixed track, a track movably supported on the fixed track, and door hangers movably supported on the movable track.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 illustrates in elevation, a door equipped with my improved hanger; Fig. 2 is a similar view with the hanger in central vertical section and the door moved to open position; Fig. 3 is a cross-section through the hanger approximately on the line 3 3 of Fig. Fig. 4c is a cross-section of the hanger on the line at i of Fig. 1; and Fig. 5 is an end view of the hanger.

In the construction of my improved hanger I preferably make use of brackets having V-shaped tracks, two of which, 10, 10, I have shown attached to the door casing in alinement, and two, 11, 11, suitably attached to the upper edge of the door. The tracks of these brackets are V-shaped and oppositely disposed, and for convenience and simplicity in construction terminate at the ends of the respective brackets, although it is obvious that the tracks of each set of brackets might, without materially changing the construction, be made in one piece, and this is at times found preferable in order to strengthen the hanger and maintain the brackets of each set in exact alinement.

ing and door is an intermediate casing or member 12 consisting, as best shown in Fig. 3, of two side plates joined together at in tervals of their length by cross-pieces 13, and inclinedinwardly at the edges to provide tracks at both the top and bottom, respectively opposed to the tracks of the brackets 10 and to the tracks of the brackets or hangers 11, sufficient space being left between the edges of the plate for the free passage of the arms of the brackets. The cross-pieces '13 are arranged on the longitudinal center of the casing and are shaped to conform to the tracks of the bracket in order that the latter may freely move thereover.

The ends of the casing 12 have inwardlyturned portions 1 f, so as to provide stops; and stops 15 are also provided at the inside of the casing at opposite ends, against which the brackets attached to the door contact, in moving the door from one extreme position to the other. Placed between the track of each bracket and one of the tracks of the member or casing 12 is a bearing-ball or roller 16, the same being unattached and freely movable, whereby it travels lineally with respect to both the fixed and movable portions of the hanger in moving the door back and forth. In order that the rollers 16 may freely revolve during the entire sliding period of the door, and the door be not overbalanced in its extreme positions, the effective length of the tracks of each bracket should be approximately equal to one-quarter the width of the door plus the thickness of the roller, and the fixed brackets 10 should be arranged approximately one-quarter the width of the door inwardly of the extreme positions of movement, and the brackets 11 located near the vertical edges of the door. By this construction and arrangement, when the door is closed, the bearing rollers 16 will contact with the arms at one side of the brackets, and when the door is moved to a fully open position, the bearing rollers will contact with the opposite arms of the brackets; in this movement of the door, the rolling takes place first between the brackets 11 and the casing 12, which continues until one of the brackets 11 strikes the adjacent stop 15, when the rolling takes place between the casing and the brackets 10. Should any 1 of the rollers become deranged or shifted from their natural positions, this will be rectified when the door is moved to one of its extreme positions.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. The combination of a fixed track, a member having two tracks, with one of the tracks movably supported on the fixed track, and a door hanger movably supported on the other track of the said member.

2. The combination of a fixed track, a door hanger having amovable track, a member having tracks respectively opposed to the fixed and movable tracks, and rollers interposed between the tracks of said member and the other mentioned tracks. v

3. In a door hanger, a casing having an upper and a lower track, a fixed bracket having a track opposed to the upper track of the casing, a movable bracket having a track opposed to the lower track of the 021s ing, bearing rollers interposed between the tracks of the casing and the other mentioned track, and a stop arranged at each end of the casing in the path of the movable bracket.

at. in a door hanger, the combination of a casing having upper and lower V-shaped tracks, a fixed bracket and a movable bracket having V-shaped tracks respectively opposed to the upper and lower tracks of the casing, and rollers interposed between the tracks of the casing and the tracks of the fixed and movable brackets.

5. The combination of a door, a fixed support arranged above the door, a support lineally movable on the fixed support, and a support attached to the door and movable on the movable support.

In testimony whereof I have signed my name to this specification in the presence 01 two subscribing witnesses.
